CustomHook

ArbitrumRegistered

A Uniswap v4 hook that restricts swaps to an owner-managed router allowlist, enforces unidirectional TOKEN_B-to-ETH exact-input swaps priced by an external oracle, gates liquidity additions behind a whitelist contract, and accumulates TOKEN_B swap credits for periodic on-chain burning.

What it can do

Runs code on every swap

Its code executes inside each trade in pools that use it.

Can take tokens from swaps

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.

Gates who can add liquidity

It checks every deposit before it goes in.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
